Original application filed May 13, 1904, Serial No, 207,869. Divided and this application filed-December 9, 1904, Serial No. 236,193. Renewed October 13, 1908. Serial No. 457,531.

to machines for vending liquids in which the dischar e is controlled by one or more valves, althou the same may be applied to various other vending machines.

It is my object to produce a simple and eifective coin mechanism without using springs and other mechanical means which are apt to become disabled by the varied use of many persons who treat the machine to various This-uses.

In the drawing forming part -oi" this s )ccifi'cationFig'ure' 1 is a sectional view oi my improvements a plied to a liquid dispensing machine in which the lever is shown in a osition at the timeof inserting the coin. ig. 2 is a similar view with the lever in its innermost position. Fig. 3 is a partly sectional view. taken on the line 3-3 of Fig. 4. Fig. 4 is a sectional view taken on the line 44 of Fig. 3. Fig. 5 is an end view partly in section of the coin engaging and releasing means. Fig. 6 is a side view of the same. Fig. 7 shows the position of the coin in relation to its engaging means.

Similar numerals of reference indicate cor res onding parts throughout.

a means for governing the inflow and outflow of the liquid in the measuring on of a liquid dispensing machine to which have applied my improvements, and which is illustrated in the original application referred to herein, I preferably employ apair of valves 42such as shown in Figs. 1, 2, 3, and 4, both valves being operated by a single lever. Each of these valves is a two-wa valve, ada ted, when in one position, to a mit liqui into the measuring cup, and, when in the other position, to allow the liquid to flow out of said cup.

For operating the valves, 1 provide a lever 50, the upper end of which is arranged to be operated by coin controlled mechanism, which I will describe separately, and is fulcrumed at its lower end 51 by means of a I pin 52 to the two uprights 48.

The lower end of this lever, is adapted to engage with two spindles 46, which actuates the valve 42, and consists of a pair of angular shoulders such as 51, the latter being slanting, so that when it is forced into contact with one of the s indles 46, the latter is thereby forced inward y, and the valve unseated. The end of the lever 50 is provided on each side with a projection of two difieren't lengths, the two surfaces of which are connected by the slanting surface 51, so that the movement of the lever will cause the ends of the spin-- dles to be moved in and out as the projecting surfaces of the lever 50 moves across the ends thereof. Byreve'rsing the position of these shoulders on each side of the lever, the lever may have a normal position such as is shown in Fig. 3 and when the lever is thrust beyond this normal position, in one direction, one of the spindles is forced inwardly, while, when it is in the odposite direction, the spindle will be release and the other one moved inwardly, so that one cock will be opened, while the other is closed.

In Fig. 1 the lever is shown as brought forward in the position necessary to '0' en the cock and )ipe 23, while in Fig.2, t e lever is shown in the position necessary to open the cock and pipe 49.

As a means for operating the lever 50 by coin mechanism, I provide a reciprocating k'n'ob or the like, 53 secured to a reciprocating push-rod 54, which latter is provided with an suitable support connected with the ca met. The push-rod is made hollow at 55 for at least a portion of its length to receive the arm 56 which is fulcrumed to the lever 50 at 57, the arm being adapted to move freely in the opening 55. A vertical aperture 57 of the proper size to receive the coin by which the mechanism is operated, is provided in the ush-rod 54 at such a lace that when the ever is drawn out to its ullest extent, the aperture will extend beyond the collar 58, as shown in the o sition in Fig. 1. When the coin is inserte in this aperture, it engages the arm 56, upon the return movement of the reciprocating pushrod 54, and this forces the lever 50 into the position shown in Fig. 2, and operates the valves'as heretofore described. If no coin be inserted it will be understood that the lever 50 would not operate to open the valves.

in order to engage the coin and to prevent the use of coins of a wrong size or shape, I provide a sliding piece 59 which, when the push-rod is ulled forward, is forced into a position which will leave the space in the slot 57, of the size necessary to engage the coin of the dimensionrequired. If any-- is pulled outwardly from the position shown in Fig. 2 the end 64 trips on the arm 65, withdrawing the slidin piece 59, and dis-engag ing the coin, whic atter may drop in any receptacle such as 66. An arm 67 is attached to the push-rod 54 and passes behind the lever to engage the latter in the forward movement of the lever 54.

. To illustrate the operation of the mechanism the knob on the outside of the cabinet is pulled outwardly as shown in Fig. 1, the arm 67 on the reciprocating push-rod causing the lever to move forward with it, and open the valve 40, to allow the liquid to pass into the measuring cup. in the slot 57, where it is held by the member 59, engage with the arm 56 which when the push-rod 54 is forced inwardly forces the arms inwardl and the lever 50 is caused to move inward y to its foremost position, as shown in Fig. 2, when the opposite cock is opened, and the liquid passes out of the measuring cup, through the pipe 49, and into the glass. The coin may remain in this 0- sition until any time that the knob is uLed forward again for a second use, when t 1e end 64 on the releasing lever turns on the arm 65, thereby withdrawing the slide 59 and re- The coin is then inserted leasing'the coin, The operation is repeated any number of times. The slide 59 is reclaim is 1. A coin-operated vending machine, comprising a reciprocatory rod, hollow at one end and having a transverse coin-receiving slot, a lever operatively connected to the vending machine, a link in the said hollow portion of said rod and pivotally connected to said lever, said link being adapted to be moved in one direction by said rod when a coin is resent in said slot, and means on said rod ior moving said link in the opposite direction.

2. In a liquid dispensing apparatus, the combination of a valve-operating lever, a link connected thereto, a push-rod having a longitudinal o ening adapted to receive said link, said rod aving a coin-receiving slot, a member adapted to engage the coin, and means on said rod to operate the latter to engage and disengage the coin.

3. In a liquid dispensing apparatus, the combination of a valve-operating lever, a link connected thereto, a reciprocatory rod having a longitudinal opening in which said link can move' and a transverse coin-receiving slot, a sliding piece adapted to engage the coin, and alever pivotally mounted on said rod and adapted to operate said coinrengaging means.

4. In a coin operating mechanism, the combination of a ush-rod 54 having a coin receiving slot,asli ing iece 59, alever 60 fulcrumed to the push-r0 and means for tripping said lever in the reciprocation of said push-rod.
